We must begin with the fact that the simplest organisms appeared long ago and are the oldest inhabitants of the planet. Throughout their existence, they have been incredibly resilient to various trials. They can survive even in the most dangerous environment.
These microorganisms have chosen a very suitable path of existence for themselves - especially parasitism in the human body. As mentioned earlier, these microorganisms are incredibly "harmful" and persistent, so sometimes it is so difficult to get rid of them.
There are several types of parasitic "dwellings". The first type includes endogenous microorganisms, ie those present in the human body. The second type includes exogenous parasites that are easily "settled" on the skin and cause various skin diseases.
Types of protozoan parasites
There are 4 types of parasites that "live well" in the human body.
Flagellate
These include lamblia, trypanosomes. This class is representative of the oldest representatives of parasites. It got its name from the organ of action: the flagella. The parasites themselves are simply microscopic, have a stable shape and, as a rule, multiply by dividing into two parts.
They are very dangerous for humans and animals, and if they fall on their bodies, they cause great harm. They also cause various diseases. Like American carotid fever, skin leishmaniasis and many others. They can parasitize in the intestines, blood and skin. Thus, it has a negative impact on human health.
Sportswear
This type of protozoan parasite has a very complex development path. The class is now known to have about 1, 400 species. All representatives "choose" a parasitic lifestyle and are extremely dangerous to humans and animals. Reproduction occurs by cell division.
Often, the tissues and organs of a person or animal are chosen as the "habitat. "This species causes many diseases. For example, malaria, toxoplasmosis.
Ciliates
These include balantidia. There are about 7, 000 different species. The locomotor organs of these parasites are the eyelashes.
A feature of this type is the presence of two nuclei. They have a permanent body shape and shell. Reproduction is usually by division. This species is less dangerous to humans and animals than the previous two species.
Sarcode
These include the amoeba of dysentery. They are the most primitive of all species and classes. There are about 10, 000 different species! There is no permanent body image. Parasitizes in humans and animals.
They often choose the digestive system for their activities. Because of this, a person can experience very serious poisoning. In some cases, deaths are also common.
These types combine high resistance to various "tests". As a result, an infected person constantly tries to fight the parasites, but it does not always work because they can tolerate all the measures.
Why they are dangerous, what diseases they cause
The simplest parasites are really very dangerous to human health. They can cause a variety of diseases that have certain consequences. Under no circumstances should you underestimate the simplest parasites, as they can cause significant harm to a person.
Diseases caused by protozoan parasites:
Malaria
Such a disease is characterized by certain differences. Sometimes there is relief, then the relief is replaced by worsening symptoms. The main symptoms are headache, fever, nausea, vomiting, convulsions.
For many years, the hit was considered the best treatment. However, deaths from this disease are often present in areas where medicine is poorly developed.
Amebiasis
Another less dangerous disease, the consequences of which can be sad. The causative agent of the disease is dysentery amoeba.
Symptoms begin to appear 7 to 10 days after infection. These can include headaches, general weakness, fever, and stomach upset in some people. This is followed by complications expressed in liver problems. If the patient does not start treatment on time and does not consult a specialist, the result will be irreversible.
Toxoplasmosis
The causative agent of the disease is Gondia's Toxoplasma. Symptoms of this disease include damage to the eyes, nervous system and cardiovascular system. Very often, in the first place, the infection is not as noticeable as a common cold.
Infection is very dangerous during pregnancy. Even if the child survives, it is likely that there will be complications and damage to the eyes or nervous system. Thus, it is important to consult such a doctor at the first symptoms.
Balantidiyaz
It is caused by a microorganism such as balantidia. Symptoms of this disease are abdominal pain, indigestion. In some cases, a high temperature, intoxication of the body is also possible.
Leishmaniasis
Leishmaniasis is considered to be the cause of this disease. Ulcers appear with skin and mucocutaneous manifestations. Edema with mucocutaneous manifestations can often occur. These diseases can be fatal because they are associated with the respiratory tract.
Leishmaniasis occurs mainly in warm countries. The disease is quite common and occurs in 87 countries.
As you can see, the simplest parasites are incredibly dangerous to human health, despite the simple structure of microorganisms. It can cause irreparable damage to the human body, as well as cause certain consequences and complications.
How are they transmitted?
There are 4 most common ways of infection:
- Contact - home. . . This type manifests itself due to violation of sanitary measures or hygiene rules. Infection can occur from a variety of activities: contact with other people's belongings, especially personal hygiene products, utensils, etc. Use. Therefore, it is very important to follow the rules of personal hygiene, to have your own personal care products, and under no circumstances should you use someone else's products.
- Feces - oral. . . This type occurs as a result of contact with feces or vomit. The simplest parasite first enters the hands or food of the "new host" and then the body.
- From food. . . This type of contaminated food manifests itself as a result of eating. It can be poorly cooked fish or meat, unwashed vegetables and fruits, dairy products.
- It is transmitted. . . This type occurs during a bite from an infected body, ie as a result of transmission through saliva.
How to get rid of them
This question no doubt arises after reading the article. Infection with the simplest parasites is very common, so getting rid of them is incredibly important.
As mentioned earlier, you should see a doctor when the first symptoms of an infection appear. The specialist may schedule certain tests and examinations. After passing them, the doctor will make an accurate diagnosis. After that, you need to start treatment immediately. Self-medication is also not recommended, as it is a specialist who can help make a correct diagnosis and prescribe an appropriate treatment. In most cases, doctors use various drugs to help eliminate parasites and speed up a person's recovery.
In modern times, there are many different good medicines that help with infections with protozoa parasites. There are many drugs on the market that allow you to find the right drug for a particular patient.
Preventive measures
It is important to follow certain rules and take preventive measures to avoid the above problems.
The most effective rules are the ones taught by children at school. First of all, do not forget to wash fruits and vegetables thoroughly. You can heat treatment or cut the skin.
In addition, you can not eat raw fish, not fully cooked meat. In order to cook the product completely, it is important to prepare the food completely, to follow the heating mode and time. Casual sex should be avoided. You should also undergo regular medical examinations.
